This book was released on 1966 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of boron additions on the physical and mechanical properties of arc-melted tungsten and a tungsten -1 percent tantalum alloy were investigated. Boron additions significantly refined the arc-melted grain size of tungsten. The 1-hour recrystallization temperature was initially increased by small boron additions (approx. 0.01 atomic percent boron), after which it decreased continuously with increasing boron content. High-temperature tensile tests showed that the boron additions produced an initial rapid rise in strength followed by a leveling off of the strength-composition curve. Boron in solid solution was postulated to be the cause of the rapid increase in strength.

Book Synopsis Effect of Alloying on Grain Refinement of Electron-beam-melted Tungsten by : Walter R. Witzke
Download or read book Effect of Alloying on Grain Refinement of Electron-beam-melted Tungsten written by Walter R. Witzke and published by . This book was released on 1966 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ingot structures resulting from electron-beam melting of tungsten consist mainly of columnar grains extending the length of the ingot. In order to examine the grain refining capabilities of various elemental and refractory compound additions, small ingots of tungsten containing these additions were prepared by electron-beam melting. Measurements on transverse ingot sections from each melt indicated that all the additions decreased the average grain diameter of the columnar grains typical of electron-beam melted tungsten and that grain refining effectiveness varied with the concentration of the solute S. Losses of the additions during melting were in excess of 90 percent in many cases. The most potent grain refiner was boron. A nominal addition of 0. 5 weight percent decreased the average grain diameter of the columnar grains from 0. 48 to 0. 008 centimeter. The effectiveness of the elemental additions decreased in the following order: boron, yttrium, carbon, hafnium, zirconium, molybdenum, columbium, rhenium, and tantalum. The losses of these elements during melting also decreased in approximately the same order. The elemental additions were generally more effective grain refiners than the refractory compounds. The elements with the smallest distribution coefficients were the most effective grain refiners.
